Subject: Quick trip to Vienna and Budapest

I have a last minute business trip planned next week to Vienna and Budapest and will have evenings and couple days free in each city. I have never been to Budapest and it's been about 20 years since I last visited Vienna while in college, so I am very out of date.

Can anyone give me a quick run down of "must" things to see and do while there and possibly small local restaurant recommendations with memorable atmosphere. I know this is a rush, but any information would help.

Thanks All! Roger, Denver, CO
